SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 403,810, dated May 21,1889.

Application led February 2G, 1889. Serial No. 301,230. (No model.)

locking or holding the sashes of a window at any desired point.

The invention is alike applicable to windows with or without weights,and comprises means -whereby the upper sash of a window where weightsare not employed can be held locked while the lower sash is unlocked.

The invention also comprises the details of construction, combination,and arrangement of parts, substantially as hereinafterfully set forth,and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a view of a section 01": awindow with my improved sash-fastener secured thereto. Fig. 2 is a rearview thereof. Fig. 3 is a detailview of one of the catches and itsoperating-dog. Fig. 4 is aview of a modited form of said dog.

Referring to the drawings, A designates a plate which is set in the jamb of awindow at the point where the two sashes overlap, as indicatedin Fig. 1.

B is a rod loosely secured to the rear side of this plate, the samebeing held or supported by apertured ears or lugs a a', attached To thisrod B is secured, fast therewith, the upper end of a catch, C, forlocking the lower sash, C', ihe lower angular end of said catch beingextended through an aperture, b, in plate A, and is designed to engage arack-bar, b', secured to the side of the window-sash C. A spring, D, issecured at one end to plate A, its lower end bearing against a tongue,d, of catch C. The office of this spring is to hold the catch O inengagement with the rack-bar bA E is a second catch for holding orlocking the upper sash, E. This catch E is loosely secured or pivoted ona cross-rod, e, of two of the apertured ears a a', the upper angular endof said catch being projected through a second aperture, e', of plate A,and engagesa rack-bar, e2, of the window-sash E. This upper catch, E, isoperated by a dog, F, rigidly secured to rod B, the upper end of saiddog being provided with end shoulders, f f, which come in contact with atongue, f', projecting from the lower end of catch E between saidshoulders.

For windows where weights are not employed, I use the form of dog abovedescribed, and shown in Fig. 3, while in windows where weights areattached to the sashes the form of dog shown in Fig. et is adopted. Theformer construction permits the upper sash to be held locked, while thelower is unlocked; but where weights are used such is not necessary. Thelatter construction provides for the simultaneous operation of thecatches, both shoulders ff being always in contact with the tongues f. Aringer-bar, G, is rigidly secured to rod B, and is extended through anaperture of plate A, so that the parts can be operated.

It will be seen that by pressing down to a limited extent on thelinger-bar G rod B will be caused to make a partial revolution,withdrawing the protruding end of catch C from engagement with therack-bar of the lower sash, and by further pressure on bar G the dog Fwill 'be made to act on the lower end of the catch, withdrawing theupper end thereof, and permit the moving of the upper sash. Immediatelyupon releasing the pressure from bar G the spring D will instantlyreturn the parts to their former position.

ABy means of my invention the respective sashes of a window can be irmlylocked at any desired point.

The principal advantage of my invention lies in the simplicity anddurability of the part-s, which are not liable to easily get out oforder or to become suddenly deranged.

I claim as my inventionl. As an improvement in sash-fasteners, thecombination of the pivoted rod and the upper and lower catches, thelatter being secured to said rod and operated in advance ot' the former,which is pivoted independent of said rod, substantially as set forth.
